Fan-out with Hera Runner and multiple parameters

[bieniekmateusz]

@script(...)
def work_script(model: MyModel) -> MyModel

And I call it via with_param

work_script(
      with_param=previous_script.get_result_as('model')
  )

This works fine. However, I would like to be able to send more config models separately. But when I add more parameters, the model breaks down:

@script(...)
def work_script(model: MyModel, params: MyParams) -> MyModel

And then I call it:

work_script(
      arguments={
          "params": MyParams()
      },
      with_param=previous_script.get_result_as('model')
  )

I can't see in the logs any clear message as to what is happening. Is it possible to parallelise while leaving a line of parameters on the side?

Solved, I found the answer in the documentation. I have to tell Hera which argument is parallelised with {{item}}:

work_script(
        arguments={
            "model": "{{item}}",
            "params": MyParams(),
        },
        with_param=previous_script.get_result_as('record')
    )
